Dextran
Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1-6) linkages. The remaining a(1-3) linkages account for the branching of dextran. Conflicting data on the branch lengths implies that the average branch length is less than three...
Fluorescein Isothiocyanate-Dextran
Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(166) linkages. The remaining (163) linkages account for the branching of dextran.
Dopamine, Norepinephrine and Ephinephrine Synthesis
Dopamine-β-hydroxylase is located inside amine storage vesicles of norepinephrine neurons. Dopamine is actively transported from the cytoplasm into the vesicles. As the enzyme is a copper containing protein, its activity can be inhibited by copper chelating agents, such as diethyldithiocarbamate...
FAK
The focal adhesion kinase (FAK) is a cytoplasmic protein tyrosine kinase that distinctly co-localizes with integrins at sites of attachment to their ligands.
Graphene-Based Composites and their Unique Renewable Energy Applications
Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.
miRNA (microRNA) Introduction
Mature microRNAs (miRNAs) are a class of naturally occurring, small non-coding RNA molecules, about 21-25 nucleotides in length. MicroRNAs are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to downregulate gene expression...
